13 Claims.

This invention relates to motion devices and while it is described withreference to motion devices for animations, particularly for advertisingand exhibition purposes, the embodiments of the invention need not be soconi-ined but may be used wherever a motion device of the typeillustrated will find application.

The principal object of the invention is to provide a simple andinexpensive motion device capable of producing a plurality of relativelyselectable movements. The devices Villustrated can produce the followingmotions; singly, or in combinations: (a) continuous rotary, (b)intermittent rotary, and (c) oscillatory rotary.

A further object of the invention is to provide a motion device which isreadily detachable from and attachable to a display board and properlyoriented with respect thereto, all without requiring the services of askilled mechanic or electrician. A motion device thus constructed isparticularly valuable since it permits an exhibitor, having only onesuch motion device, to use the same with a series of different displays,whereby -he can change from one display to another, without losing theadvantages of animation, and without being forced to the expense ofhiring a skilled mechanic when changeover is desired.

A further object is to provide a motion device having a plurality ofoperating shafts of each of which, either or both ends can be utilizedfor animation, if desired. At some times, on one end of a shaft can bemounted an animation element, and on the other can be mounted acounterbalancing means. At other times, if desired, both ends of a shaftmay be used for animation, in the event that opposite sides of acombined display are designed for animation.

A still further object is to provide, in combination with an animationmotion device, means whereby in the assembly oi the device to a display,proper coordination of the device and the animatable part of the displaymay be readily, easily, and accurately eiected.

A still further object is to provide an animation motion device whereinthe three movements above specified, or other equivalent movements, maybe interchangeable and selectable, interchange and selection beingeiiected easily and with simplicity.

A still further object is to provide an animation motion deviceproducing concurrently several different motions, one or more of whichmay be sethat it can be concealed by a relatively small display panel, apart of which is to be animated.

A still further object is to provide an animation motion device whereinthe parts are so constructed that the problem of lubrication is notpresented, there being no lubrication required during the normalmaintenance of the device.

A further object is to provide a motion device which can be operatedwhile upright, to rotate an animatable part in a vertical plane, orwhile lying on its side to rotate an animatable part in a horizontalplane.

Still further objects will be readily apparent to those skilled in theart upon reference to the appended drawings showing an embodiment of theinvention, hereafter described in detail. In these drawings,

Figs. 1-7

Referring to the drawings, wherein like reference numerals refer to likeparts, it will be seen Kthat the motion device of Figs. 1-7 includes acasing made of two parts, referenced II (front) and I2 (back), thesebeing joined by suitable transverse bolts, indicated at I4, and havingtheir head and nut ends seated in recesses I5 formedinthe walls of thecasing sections. Suitable dowel vpins are also provided on the juncturesurface line I6 to align the casing sections properly with respect toeach other when they are to be joined. At one side of the casing,cooperating notches I'I at the juncture surface line I6 provide anaperture through'whch may be passed a conductor I8 for conductingelectrical current to the hereinafter described velectrical partsdisposed within the casing.

The device here shown is factory made and is intended to be used withany one of a number of factory made displays, and since it is avprerequisite that a display be properly oriented to the operating partsofthe device, which happen to .be shaft ends, means are provided fororienting the device here shown to a display so that proper connectionmay be effected .readily and without difficulty, andsuch means will nowbe described.

The casing is provided with six through-tapped bosses 20 to 25asymmetrically positioned .to facilitate orientation thereto of adisplay, whose .animatable part or parts isor are to be operativelyconnected to any one or ones of the three operating shafts 30,!3I, 32,which are journalled .in opposite casing walls, and whose ends projectfrom the front and back of the casing, as indi- .cated in Fig. .2. Thisconstruction insures the animatable part being 4properly oriented to theproper one of the ends of `the vthree shafts.

Themechanism of Vthe device will now be described.

Disposed within the casing and energized by the current fed thereto bytheconductor I8 is a :synchronous motor 40, supported in -a suitablemanner, as by means of a bracket 4I in turn` isecuredto .the casing wallby suitable fastening means, such as the studs 42. On the end of thelmotor 'shaft-43 .is xed a -worm 44 .in constant mesh with a helicalgear which is-centra11y and coaxially .xed to the continuous rotaryshaft 3|.

;It will be observed thatin the operation of the device, the shaft 3lrotates continuously and at a relatively slow .speed compared with thespeed of the motor, the speed reduction being effected `throughthemedium of the worm and gear.

Fixed to and traversing the rotary Ashaft 3I, andin back of -the gear45, is an eccentric plate 5I which fits within the cross head flangesV52 of anv eccentric strap 5'3, these flanges being parallel to the axisof the rotary shaft 3| and being formed intermediate` the endsofxtheeccentric strap, there being an aperture 53a in the cross headto provideu clearanoe for the shaft .v3 I

One end of the eccentric strap is apertured at -54 to 'permit 'thepassage therethrough of the intermittent rotary :shaft 30 rand Vtheconnection :betweenthe.eccentric:strap 53and the shaft 30 provides ajournal for that end of the eccentric lstrap. -The "other fend oftheeccentric strap is lating arm 5'I lwhich in-turn is xe'd to theAoscillating shaft 32. It will be apparent that rotation of the rotaryshaft 3| causes the eccentric strap to rock on the axis of theintermittent rotary shaft 38 as a pivot, and that such rocking of theeccentric strap causes rocking of the arm 51 about the axis of theoscillating shaft 32 as a pivot, which, in turn, due to the fixedconnection between the arm 51 and the shaft 32, causes a rocking oroscillating motion of the oscillating shaft 32.

Near the front of the casing there is fixed to the oscillating shaft 32a second arm 6I (Fig. 5) whose free end is pivotally connected, by meansof a pin S2, to the end of a reciprocating link 63.

'The other end of this` link is provided with a pin 634 adapted to seatitself within the notches of a six tooth ratchet 65, which is fixed tothe intermittent rotary shaft 30. A coil spring 61, woun-d around theoscillating shaft 32 adjacent the arm 6I, with one of its ends 68engaged by a wall of the casing section I I and with the other of itsends E9 engaging the link 63, biases the link 63 downwardly so that itspin B4 will be constantly urged towards the .bottom of the notch 65 inthe ratchet 66 in which this pin happens to nd itself.

Itwill be apparent Vthat the continuous rotation of the rotary shaft 3Iand the oscillation of the oscillating shaft 32 will be translated intointermittent rotary motion of the intermittent rotating shaft 3Q, withthe timing of the parts be- I,"

`other of whose ends is hooked around one of the bolts I4 that securecasing halves to each other. It will vbe observed from the foregoingthat there isprovided asirnple, inexpensive motion device which can beoperated economically on al- 1 ternating current Athrough the medium ofthe inexpensive :synchronous motor 40 to provide three. relativelyselectable animation motions.

It will the also observed that these motions are concurrent, andtherefore it can clearly be understood that two or more motions may beutilized at any one time, creating a display that is far more effectivethan if but one motion were provided for it.

Fig. '7.shows,'diagrammaticallv how theratchet 66 .may be utilized as asynchronized flasher device to flash the lamps'L of the display throughthe medium of contacts engaged by the tips oi the ratchet teeth, all tocreate a more effective display.

Figs. 8-13 The device of Figs. 8 to 13 functions like the device ofFigs. 1 to 7 but is much simpler in its construction and thereforebetter adapted for commercial use. made of two parts, referenced III andII2, of which the former is the front section and the latter is the rearsection. The two sections are joined by suitable traversing bolts H4having on their ends spacer-nuts IIE.

Suitably positioned in the right side wall of the back section II2 areholes IIS lined with snapin lrubber grommets IIS, these providing accessholes for the two pairs of conductors which pass through the right sidewall of the casing, one pair It includes a box-like casing Cil going tothe 'source of electrical supply and the other pair going to a lamp orlamps to be flashed by a part of the device, all as will be describedmore in detail at a later stage in this specification.

Passing through the front and back walls of the casing are four shaftsreferenced respectively |2|, |22, |23, |24. These four shafts are theoperating shafts of the device, and provide the following motions:|2|continuous rotary at a high speed; |22-oscillatory rotary; |23-intermittent or step-by-step rotary; and |24-continuous rotary at a lowspeed. Suitable bearings are provided for these shafts in the front andback walls of the casing, for journalling and thrust purposes and eachbearing includes a bearing ring |25 fixed in a boss |25a of the casing,and a thrust collar |2511 pinned to the shaft by a pin |25c, as shown inFig. l1. Washers |25d separate the rings |25 from the collars |251).

Disposed within the casing and energized by the current fed thereto fromthe source of supply, is a motor |26 contained and supported in wideshallow recesses |21 formed in the front and back walls, the motorhaving a vertical shaft |26 projecting from the upper and lower surfacesof the motor. To the upper end of the shaft |28, through the medium of acoil spring coupling |29 which compensates for shaft misalignments, iscoupled a shaft |3| having thereon a worm |32 in constant mesh with agear |33 xed to the continuous rotary high speed shaft I2 The shaft |3|,its worm |32, and the gear |33, are disposed within a lubricant-filledsub-casing |34 which is secured with respect to the main casing by meansof the shaft |2|, which at its ends is journalled in the main casing,and which passes through bosses |34a in the sub-casing, the holes in thebosses providing a press fit between them and the shaft |2|.

The shaft |3| is journalled in bearing rings |34b xed inthe sub-casingand is provided with a. thrust collar |340 pinned thereto by a pin |34d,the bearing rings properly journalling the shaft |3| and also preventingescape of the lubricant in the casing, and the collars preventingendwise thrust of the'shaft |3|. The end of the casing is closed by ametal disk |340, of the snap-in or Welsh plug type.

It will be observed that in the operation of the device, the shaft |2|rotates continuously at a relatively high speed, since it is permanentlyconnected to the motor; the ratio of the speed of shaft |2| to that ofthe motor will of course be determined by the ratio of the worm and gearteeth, in accordance with the desires of the manufacturer of the device.

Fixed to and traversing the continuous rotary high speed shaft |2| andin back of the gear |33 is a pinion gear |35 in mesh with a large spurgear |35 fixed to the continuous rotary slow speed shaft |24 and thegear train thus created will provide for the shaft |24 a rotation in adirection opposite to and at a lower speed than that of the continuousrotary high speed shaft |2 Fixed to and traversing the continuous rotarylow speed shaft |24 is an eccentric |38 which nts within the hole of aneccentric plate |30, the latter at the end thereof remote from the shaft|24, being connected by a pin |4| to a rocker arm |42 which traversesand is xed to the oscillatory rotary shaft |22.

It will be readily seen tation of the shaft |24 will cause the arm thatthe continuous rorock back and forth continuously, in turn causing -tionof the Geneva wheel constant oscillatory rotation of the oscillatoryrotary shaft |22.

Fixed to and traversing the continuous slow speed rotary shaft |24 is aplate |46 to which is xed an arm |41 provided with a pin |48 adapted tomesh with the slots |49 of a Geneva wheel |50 which in turn is fixed toand traverses the intermittent rotary shaft |23, the plate |46 and theGeneva wheel |50 being disposed immediately in back of the gear train|35, |36.

It will be seen that the constant rotation of the shaft |24 causes anintermittent rotary mo- |50 and accordingly of the shaft |23, andinasmuch as there are shown to be six equally spaced slots on the Genevawheel |50, it will be readily seen that the shaft |50 will rotate 60 ineach step.

In order to provide an accurately indexed intermittent rotation for theshaft |23, indexing means are provided to lock the Geneva wheel and theshaft |23 fixed thereto in place at the end of each 60 rotation, andsuch indexing means will now be described. Between the slots |49 theGeneva wheel is formed with arcuate cutouts |52 which mesh with the edgeof the plate |46, the latter having a cut out at |53 which permits theGeneva wheel teeth, |54, namely, the portions between the cutouts |52,to clear the edge of the plate |46, the whole operating in the followingmanner: As seen in Fig l2, the Geneva wheel is free to rotate clockwiseby virtue of the fact that the tooth thereof receiving the pin |48 is inthe clear space provided by the cutout |53. When the plate |46 rotatescounterclockwise, the Geneva wheel rotates clockwise 60, or until thepin E48 no longer is in a slot |49. At this time, the Geneva wheel willcome to rest and it will be locked at rest for a moment, or indexed,.due to the fact that the plate cutout |53 had cleared the .tooth |54,leaving the edge of the plate |46 again in mesh with a cutout |52 in theGeneva wheel. The operation is such that the Geneva wheelis alternatelylocked by the edge of the plate |46 and. freed by the cutout |53, sothat the Geneva wheel-can move intermittently, and yet be locked orindexed at the end of each step of rotation.

It will be apparent from the foregoing that the continuous rotation athigh speed of the shaft |2| will be translated into continuous rotationin the opposite direction and at low speed of the shaft |24, intooscillatory rotation of the shaft the shaft |24 causes an intermittentrotary mory motion of the shaft |23, and that the timing of thestep-by-step rotation corresponds to that of the oscillatory rotation.

In order to provide a properly timed and coord1nated flasher effect, theindexing shaft |23 may be utilized as follows: Positioned upon the shaft|23 near the front of the casing is a spur tooth ratchet wheel |60 Whoseteeth are adapted to engage an insulating button |6| on the spring leaf|62 of a flasher, the leaf |62 having a contact |63 adapted to engage acontact |64 on a sec 5 ond leaf |65, the circuit through the contacts|63, |64, being closed and opened alternately in accordance with theintermittent rotation of the indexing shaft |23, to provide anintermittent make and break for the circuit controlled by the F flasher,properly timed to the indexing rotation.

The electrical connections of the device are as follows: The device isprovided with a plurality of bolt-studs |66 which mount bus bar straps|61 on the casing side adjacent the holes ||8 and threaded into bossesof these straps are binding screws a, b, c, and d, to the for-mer pairof which are connected the conductors |10 connected to the supply plugI1I, the conductors passing through holes H8 and a grommet IIS. Themotor I 26 is connected to these binding posts through its leads l's'iaand is accordingly placed across the line. The flasher anchoragecomprises binding posts |12, |13; to the post |12 is connected one ofthe leads 14 which goes to the flasher lamp |15 outside of the casingthrough a hole H8; the other post |13 is connected by a bus bar |16 tothe binding screw c. The flasher lamp |15 is connected in series withthe flasher switch through the medium of the conductors |14, one ofwhich is connected to the binding post |12 and the other of which isconnected to the binding screw d, these conductors passing through ahole IIS and a grommet ||9.

The flasher lamp is flashed through the medium of the interruptedcircuit controlled by the flasher contacts |63, |64. A condenser |11 isconnected across the flasher switch and lamp through the leads |18 whichconnect the condenser to the binding screws b and d.

The nuts on the ends of the bolts I I4 which pass thro-ugh the casingfrom front to back thereof are disposed in rubber blocks |89 and thesehave grooves |90 which permit a display panel or panels to be positionedalong either the front or back wall, or both of the device, the displaypanel or panels in turn holding the device in place through theinterlock provided by the fact that the edges of holes' in the displaywall are disposed in the grooves |90.

In the side walls of the casing there are a plurality of apertures intowhich are snapped rubber blocks I9I similar to those at I 89, theseblocks having grommet like ends |92, which anchor the rub-ber blocks |9|to the side walls of the c'asing at these points. These blocks may beutilized as panel connections orV as cushion supports for the device inthe event the device is disposed on a side for use with its motor shaftI 28 disposed horizontally rather than vertically.

Under such circumstances it might be desirable to have an animationeffect produced by the high speed motor shaft |28, and for this reasonit is contemplated to extend the motor shaft |28 through the bottom ofthe casing, to provide a constantly rotating high speed shaft end, whosespeed is greater than that of the shaft |2|.

It will also be observed that the casing is provided with Ventilatingair ports I 94 through which air for cooling the motor |26 may becirculated, the circulation being induced by the fan |95 on the motorshaft |28 near the casing bottom. These vent ports are large enough tofacilitate inspection of the device, whenever desired.

In order to provide a further animation effect, the device may be usedto rotate a horizontal turntable, as disclosed in Fig. l5, which shows aturntable |93 connected to an end of a shaft, such as shaft |24, so asto rotate slowly, the device lying on its back or front with its shafts|2||24 vertical, and cushioned on its blocks |89. The turntable is shownas having terraces |99 which facilitate centering of a load placedthereon. The importance of the thrust bearing arrangement at |25 for theshafts |2||24 is readily apparent in this connection, since thesebearings will support the load on the table.

All display panels with which the device is to be used will have a holeor holes through which connection is effected to one or more of theshafts I2I-I24, in addition to the holes for the rubber blocks |89, andby virtue of the fact that the panel shaft holes will be properlypreoriented to the panel block holes, and by virtue of the fact that theshafts |2||24 are asymmetrically positioned with respect to the blocks|89, it will be impossible for a device tobe applied to any panel in anyway but the proper way, for if it be applied improperly, the panel shafthole or holes will not align with shaft ends, as would be the case iflthe device were applied to the panel in proper fashion.

To illustrate this feature, we have provided Figs. 11 and 16 which showa panel 200 having a single shaft hole 20| aligned with the oscillatoryrotating shaft |22. Connection to the shafts |2I, |23, and |24, cannotbe effected, since the ends of these shafts are concealed by the panel200. Connection to the shaft |22 may be effected through the hole 20|which exposes shaft |22.

It will be observed that a panel can be mounted properly only againstone surface of a device, and cannot be applied properly to anothersurface. This feature is of importance since the angular movements ofthe opposite ends of the shafts, though they are complementary, are notidentical, and very often a display will cooperate properly with oneside of the device, but not with the other. For example, the panel 200of Fig. 16, being designed to cooperate with the back end of shaft |22,can be properly applied to the back surface of the device; however, ifit be applied to the front surface of the device, it will conceal allshaft ends and it will be obvious that the application is improper.

Fig. 11 shows how an animatable part 204 may be operatively connectedthrough the hole 20| in panel 200 to the end of shaft |22. Theanimatable part is provided with a plurality of holes 204a properly andasymmetrically positioned to cooperate with similarly positioned rubbermounting blocks 205 (like the blocks |9I) disposed on the disc part 296of a coupler having a hollow collar 291 adapted to be projected througha panel shaft hole 20| and receive the end of a shaft |22. The shaft endhas a flat seat 208 for a set screw 209 passed through the collar 201which assures proper alignment and orientation of the shaft |22 to thecollar 201, and in turn to the animatable part 294.

In Figs. 18-20, the animatable part 204 is shown as a moving arm havinga shutter portion 2| 0 adapted to cover a lens 2I| behind which issupported a flasher l-amp |15.

The arrangement is such that when the arm is swung down (full lines),the lens is covered, whereas, when the arm is swung up (as shown indotted lines) the lens is exposed; the lamp is arranged to be dark whenthe lens is covered and to light when the lens is exposed.

It will be observed that the sign on panel 209 is equipped withsub-panels 2|2 mounted on and covering the rubber blocks |89 which mountthe panel, the sub-panels having on their backs, pins tted into theblocks |89.

The devices shown, as can by now be readily understood are universal intheir use, in that they can be used in an infinite number of ways withdisplay panels, and without inaccuracy of animation.

The devices shown represent improvements over the ones shown in my priorapplication Serial No. 657,649, filed February 20, 1933, of which thepresent application may be regarded as a continuation in part.

Now having described an embodiment of the invention, lreference will behad to the appended claims for a determination of the scope o-f theinvention.
